Disable request cache for streaming and other fixes

[rishabhmaurya]

Description

When request is streaming aggregation, we should refrain from caching it due to lack of better solution at present.

Independent of this issue, there are couple of other issues with streaming aggregation which are follow up of #19484 -

Need to check flush mode as null or per segment before deciding on StreamCardinalityAggregator in CardinalityAggregatorFactory.
Minor - When profilingAggregator is enabled, flushMode decision doesn't work as expected.
Min, Max aggregator should be Streamable.

Manual backport 3.3: #19522

I would expect a non-null FlushMode when creating aggregator. Will figure out why later.
